Web这是一个 Keras2.0 中，Keras 层的骨架（如果你用的是旧的版本，请更新到新版）。. 你只需要实现三个方法即可: build (input_shape): 这是你定义权重的地方。. 这个方法必须设 … Generally, all layers in Keras need to know the shape of their inputsin order to be able to create their weights. So when you create a layer likethis, initially, it has no weights: It creates its weights the first time it is called on an input, since the shapeof the weights depends on the shape of the inputs: Naturally, … Meer weergeven A Sequential model is appropriate for a plain stack of layerswhere each layer has exactly one input tensor and one output tensor. Schematically, the following Sequentialmodel: is equivalent to this function: A … Meer weergeven Once your model architecture is ready, you will want to: 1. Train your model, evaluate it, and run inference. See ourguide to training & evaluation with the built-in loops … Meer weergeven You can create a Sequential model by passing a list of layers to the Sequentialconstructor: Its layers are accessible via … Meer weergeven When building a new Sequential architecture, it's useful to incrementally stacklayers with add() and frequently print model … Meer weergeven
